Worked on the fitment of my custom fender garnish... so far... so good.
Countersunk holes on backside of rear overfender to accommodate the height of the rivet nuts.... this allows the overfender to sit flush against the car body. I will also countersink the screw holes deep enough so that I can fill them later. The screws will serve the purpose of holding the overfender tight to the car body while the 3M panel bond cures. They can be taken out once cured but I'm leaving mine in.
